Question

Quizplus · Accepted Answer

The quantum number represented by the symbol $l$ is the azimuthal quantum number, which determines the shape of the orbital (thus relating to choices A, B, E) and indirectly the type of orbital (choice C). It does not directly determine the orientation of the orbital in space; that is the role of the magnetic quantum number ($m_l$).
